METAL WEATHER STRIP.

Application filed March 5, 1923. Serial No. 622,713.

This invention relates in general to metal weather stripping, and hasmore particular reference to metal weather stripping provided upon thesash and parting strips of the window. I

A principal object of the present inven tion is the provision of aweather strip of greater and more prolonged eflicienoy than thoseheretofore in use and which may be cheaply manufactured and readilyinstalled.

One of the objects of my invention resides in providing an improvedconstruction over that shown in patent to Charles A. Shogren, No;1,195,108, of August 15, 1916, which patent discloses a complete weatherstrip including a parting bead which may be substituted bodily for theusual parting bead found in wooden window frames, andwhich parting beadincludes a weather stripping portion adapted to co-operate with acomplementary strip or strips fastened to he window sash whereby thespace between the sash and the parting strip is effectively sealed.

One of the objects of my improved construction over that shown in theafore-mentioned pate-ntresides in providing an arrangement for moreeasily attaching the weather strip to the face of this parting strip,and for also removably fastening the parting strip with its weatherstrip into the usual channel of the window casing or frame whereby itcan be quickly removedfor repair or assemble ofmy improved strip to thewindow sash. I

Still a further object of my improved invention resides in my improvedparting strip having recessed shoulders on that portion which projectsfrom the window casing, a novel. arrangement of sheet metal weatherstripping attached to the front face of the stripping and extendingoverand around the sides of the parting strip to provide lateral flangesarrange in spaced apart arrangement from the outer walls of saidshouldered recess so as to receive in such spaced portions,complementary angle strips fastened to the window sashes.

Yet another object of my invention resides in providing suchcomplementary angle strips attached to the window sashes with outerhemmed or folded edges which lie within the flanged portions of thestrip at tached to the parting strip, which hemmed edges not onlyprovide tight contact with the lateral flanges but also eliminate anyscraping action. 7

A further object of my invention is the provision of a weather strippingof this character, which, while requiring a minimum amount of metal,will possess improved protection against circulation of air through thewindow.

Numerous other objects and advantages of the invention will be apparentas it is etter understood from the following description, which, takenin connection with the accompanying drawing, discloses a preferredembodiment thereof.

Referring to the drawings,

Figure 1 is a partial perspective showing weather stripping embodying mypresent invention installed in place; and

Fig. 2 is a horizontal section on an enlarged scale through the same.

For the purpose of illustrating my invention I have shown on the drawinga portion of a. window casing or frame, indicated generally by referencecharacter 11 and particular description of which is unnecessary to anunderstanding of my present invention. It should, however, perhaps bestated that this casing is provided with the usual parting stripreceiving channels or recesses 12 and, in the present instance, rails 13provide for the sliding of two window sashes 1 1.

My improved weather strip comprises a combined parting strip and sheetmetal stripping attached thereto and adapted to co-operate withcomplementary sheet metal stripping attached to the window sashes Asclearly shown in Figure 2, the parting strip 15, which is adapted toreplace the original parting strip in the window, has its sides cut awayslightly throughout its length and from the casing or frame'properoutwardly to provide recessed shoulders. The outer face of the partingstrip is recessed, and in the present disclosed form of my invention,this recess consists of a channel or groove 17.

The weather stripping pro-per in the present preferred form of theinvention,

comprises a metal strip seated in the recess or groove and having partsextending in the form of flanges along the sides of the part ing stripin co-operative overl- Jed rel on with angle strips secured to the edgesof "he sash and extending between the flanges mentioned and the partingstrip itself. illeteronce character 18 indicates a. central. stripdepressed throughout its lingth at 19 to extend into the channel 17, theportions of the strip adjacent said channel engaging or resting againstthe outer face of the parting strip. The metal of this central stripextends out beyond the side taces of the parting strip and 's bentinwardly to form two flanges 21. Fastening means are providd within thegroove or channel 17 and these means in the present instance consistofnails or brads 22 which are driven home through the portion of theweather strip arranged in the channel or groove 17, entering into thewood thereof with the heads engaging the material of the strip adjacentthe outer edge of the recess and with the points cleated or clinchedbehind the strip.

(lo-operating wez'ither strips of angle form are indicated by referencecharacter Ono leg of this angle is secured against the side edge or faceof the sash by screws 236 or otherwise, with the angle arranged towardthe parting strip. The free edge of this leg is reinforced, convenientform of reinforcement being to fold the material back upon itself asindicated at 27.

'lhus constructed both co-operating menihers of each pair of flangeparts arr-ang ed lfctween the s: sh and parting strip are reinforced.the flange part ssociated with the windo. sash by the return told 527and the. flange part tiSSOClUiIGtl with the parting strip by closel'irin contact with its outer face.

The hennned or folded edge 27 of ea -h angle strip in addition to haringt functionof forming a tight lit with t lateral ilaii Q1 of the stripattached to the parting strip, also provides a means for limiting theoutward increment of the angle strips attached to the sashes.llxperience has shown that when an installation his been in useconsiderable time. there is a pronouncee shrinkage of the saihes in thewindow frames. In other rords. referring to Fig. 2, the sashes Ll.shrink away from the frame 11. thus moving outwardly from this frame ina direction toward the h ttoin of the drawing as shown in Fig. 2. Thisshrinking inovenent will be limited by the hemmed edges 27 of the anglestrips abutting the. i'iolded flanges .21. and since these edges areheinnied there will he no scraping action as there would he if the edgeswere raw.

It will he noted that the metal stripping other leg of the securedtogether ii interlocked relation. The arrangement 111st describedinsures ag lust deformation of the flange parts and the Stdjitl'it'tlOllof the n'ietal strip from the wood.

The parting strip is preferably secured in place by screws 28, whichscrews are shown in dotted lines in Figures 1 and 2 of thespecification, taking through the metal strippii'ig 18. the lCCQHS orgroove 17 and on through the parting strip into the casing. the head 25)of the screw engaging the metal strip 18 OPPOb'll'G the presented facesof the parting strip along side the groove. These faces 1 ray be formedor shaped. if desired. on a sligl'it rounded bevel to more closely follow the configuration of the strip 18 and. reliere any necessity forproviding sharp folds.

it will he noted from Figures 1. and 2 of the drawings that the sheetmetal stripping w i through the re-eiitraut fold of the stripoin 1' r-iit? as it nes 111 the channel or recess 17 and 1 n 7 u thence int.) theparting strip to. .hese nails or brads 522 are arran ed in s )acedrelation 7 4 1 h V "l =tudmai or the strip. In addition. 111 irerreniue's )aced relation longitudinal of m in i: he strip. the screws LS arefastened through he re-entrant fold of strip 18 as it lies in thechannel or groove 17 of the parting strip thence through the partingstrip and into the 'l'ranie ll. thereby detachably fastening raycombined unit weather stripping in place. it is thought that theinvention and many of is attendant. advantages will be underr from theforegoing description, and it )e apparent that Ytll'lOllS changes maynude in the form. construction and arrangeinent of the parts withoutdeparting from the spirit and scope of the invention or sacrificing allof its material advantages, the form hereinbefore described being merely.1 preferred enilmdiineut thereof.
